You choose to drive every day, you recognize it is potentially deadly but assess your risk for yourself. Someone may decide to go out to a bar or restaurant or AMP these days since the government has allowed them to now be open, they are assessing their risk. I won't be going any time soon, but I won't be judging others either.
As for wearing a mask while you're having sex 2 inches away from someone's face, and coming in contact with all sorts of fluids, I'm sorry the science says that's just stupid, unless you're wearing a hazmat style full body condom and a full face biochemical gas mask, your stupid mask won't save you much.
